SOLDERINGr-MACHINE.

Specification of Letters Patent.

Application tiled September 17, 1908.

Patented Jan. 3, 1911.

Serial No. 453,566.

To all whom it may concern:

Be it known that I, JULIUS BRENZINGER, a citizen of the United States,residing at Mount Vernon, in the county of lVestchester and State of NewYork, have invented certain new and useful Improvements inSoldering-Hachines, of which the following is a specification.

This invention relates generally to soldering machines, and particularlyto machines for automatically applying and distributing solder tosuitably secure together the overlapping' end edges of the formedsheet-metal blank to produce a can body.

The principal. object of the present invention is the provision of amachine which may, with few changes of parts and a minimumrc-adjustment, be quickly and easily adapted to any one of a number ofdifferent sizes and shapes of can bodies.

Incidental to the above, this invention has in view certain improvementsin machines' of this class with a view to simplifying the constructionthereof and enhancing their efficiency and dependability.

My invention will be readily understood by reference to the accompanyingdrawings, forming a part of this specification, in which- Figure 1 is aside elevation of a machine embodying my invention; Fig. 2 is a top planview thereof; Fig. 3 is an elevation of the side opposite to that shownin Fig. 1; Fig. 4 is a rear elevation of the same, with the solder-wirecoils removed; Fig. 5 is a horizontal section taken substantially on theline 4 4 of Fig. 1; Fig. 6 is an enlarged detail view, partly insection, of the cambody carrier and parts of its operating mechanism;Fig. 7 is an enlarged detail view of the soldering iron and parts of itsoperating mechanism; Fig. 8 is a partly sectional elevation of themechanism for ejecting the soldered bodies; Fig. 9 is an enlargedsectional end view of the ejecting mechanism; Fig. 10 is an enlargedsection through the rear shaft, looking' forwardly; Figs. 11 and 12 areenlarged detailed views of different parts of the solder-feed mechanism;Fig. 13 is a sectional end view of the soldering iron, and Figs. 14, 15,16, 17 and 18, are detailed views hereinafter described.

Referring now to the drawings in detail,

numeral 21 refers to the heavy supporting frame upon which the variousparts of my machine are mounted. in the lower portion of this frame, isthe power shaft 22 carrying the pulley 23, which is driven in the usualmanner from any suitable source of power. Also suitably journaled in theframe 21, and disposed at right angles to the shaft 22, is the shaft 24(best shown in Fig. 5) which is driven from the shaft 22 through themedium of the bevel gear 25 on said shaft 24 in mesh with the similargear 2G on the shaft 22. Said shaft 24 is in two parts, connected by thefrictiondrive device 167, and through the bevel gears 31 and 32,frictionally drives the vertical shaft 27, upon which is mounted thegear 28 in mesh with the gear 29 on the vertical shaft 30. It willtherefore be seen that through said friction-drive device the shaft 30may be normally rotated by said shaft 22, yet may be stopped at any timewithout stopping the shaft 22 or the mechanism connected to and drivenby the latter. These friction-drive devices or clutches are in commonuse, and as no invention is claimed for the one shown, a detaileddescription thereof is not believed to be necessary.

The shaft 30 is designed to drive the carrier for the 4formed blanks,and to this end is provided with a head 33 from which project anydesired number of radial arms 41, six being shown in the drawings. Tothe head 33, below each of these arms, is secured a supporting andretaining mandrel, of substantially the configuration of the desiredform of can body. The machine illustrated being designed to close andseal what are known as round cans, this mandrel is shown ofsubstantially cylindrical configuration. As best shown in Figs. 6, 9 and13, the mandrel 34 (and these mandrels being identical in all respects adetailed descriptio-n of one will suflice for all thereof) is hollow,with the upper face thereof in the form of an arm 35 pivoted at 3G insaid head 33. This arm 35 forms one of the arms of a bell crank lever,of which the downwardly projecting arm 37 is the other. A compressionspring 38, acting against said arm 37 and the sleeve 39 on the shaft 30,tends to keep the arm 35 normally in its elevated position, with theupper face thereof flush Suitably journaled dit with the upper face ofthe mandrel of which it then forms a part. 'lhe formed blank, theoverlapping ends of which it is desired to secure together, is designedto be slipped upon this mandrel when it is in the position indicated inFig. 2. rlhe end edges of the blank are overlapped as indicated in liig.f), with the right hand edge overlapping the left hand edge. ll`his isdone in order that the two ed'es may be held together by the edge of theblock Ll() removably secured. to the arm al, with saidv block ll()located sutilciently 'to one side to be non-interferent with theoperation of the soldering iron, hereinafter described. lhese arms andthe blocks secured thereto are so located that the block l() is in suchrelative position with respect to the mandrel 3st-, that the unsolderedblank may be slid between these two members, and upon raising of the armis securely clamped therebetween. This arm 35 is reciprocated throughmovement of the arm 37, and to effect such movement at the proper time,l provide a roller Ll2 at the end of said arm 3'?, adapted to impingeagainst the block et?) when a portion of the latter is. brought into thepath of movement of said roller. Normally, said arm is forced outwardlyby the spring 38, and the arm El and the block et() are thereby clampedtogether. ln order that the block 4:3 may be raised into the path ofmovement of said roller ft2, l pivot the former at all to the standardi5 on the frame 2l, and provide the lever-arn'i y-l6 between which andthe foot-treadle ill' a connecting rod i8 is interposed. Obviously, whensaid treadle i L9 is depressed (the latter being conveniently accessibleto the operator when the latter is in position to feed the formed blanksupon the mandrels) the arm l? will be depressed and the block raisedinto the path of movement of the roller 4t2, forcing the latter inwardlyagainst the action of the spring 3S, and thereby depressing the arm 35and permitting a formed blank to be inserted upon the n iandrel with thesuperposed end edges thereof clamped together between the arm 55 and theblock at).

ln order to prepare the overlapping edges for the soldering operation, lprovide a fluxing device which includes the swinging arm 49, adjustablymounted upon the vertical rod which is secured within the end of thebracket 5l mounted upon the frame Q1 of the machine. TWithin the freeend of the arm a9, is secured the tube at the upper end of which (notshown in the drawings) may be mounted any desired form of rosen voir orcontainer for the lluxing solution. To the lower end of the tube 5e ispivoted the plate at the bottom of which are the oppositely projectingintegral guides the upper faces of which not only properly direct theformed blank in its movement toward the mandrel, but which also formpads upon which, in any desired manner, a small quantity of the lluxingsolution is permitted to drip. lhen it is desired to feed a formed blankupon the mandrel, the end edges thereof to be soldered are slightlyseparated and passed one to each side of the plate Guides direct theedges down upon the pads .Si against which they are held'during thefeeding operation by the weight 56 at the end of the loosely pivoted arm57, which operates through the adjustable rod 58 to press said edgesagainst said pad with sutlicient firmness to cause them to take up thenecessary amount of the tiuxing solution. The formed blank is thenproperly positioned over the mandrel and clamped as explained by thearms 35 and Lll.

Rotation of the head 33, as hereinbefore explained, advances the mandrel3d: until the latter and the blank thereon have been brought into properposition under the soldering iron 59. rlhe soldering iron is suitablymounted at the end of the bar G0 which is slidable in a suitable groovein the block 6l, wherein said bar is retained by the strips 62 G2. Saidblock G1 is fixed upon the sleeve or hollow shaft G13, journaled insuitable bearings in the frame 2l of the machine. lt will therefore beapparent that upon rocking the shaft G8, the soldering iron 59 will beraised and lowered, while, at the same time, the latter may be longitudinally reciprocated through imparting a sliding movement 'to the barGO.

The soldering iron 59 is raised and lowered in the manner suggested, andsuch movement thereof properly timed, by the arm G5 fixed upon thesleeve or shaft 63 and having a roller GG at the end thereof incooperative positional relation to the cam 67 on the shaft G8, which isrotated by the pinion 69 on the shaft Q2 in mesh with the gear 70 onsaid shaft (38. ln this manner rotation of said shaft 68 will, throughthe cam (37, effect rocking movement of said shaft G3 and verticalreciprocation of said. soldering iron. Longitudinal reciproeation ofsaid soldering iron 5t? at the proper' time, is eli'ected through themedium of an arm il having a slot 72 within which rides the pin 73 atthe end of said bar (SO. To the other end of said bar Tl is pivoted thearm 74 of a lever pivoted upon the stud or shaft T5, the other arm 75 ofwhich is provided with a roller 77 operating in the cam-groove T8 of thecam 79. lt will be noted that this cam-groove YS has a substantiallysemi-circular portion, and that when said roller is in saidsei'ni-circular portion the cam 67 has operated against the roller 66 ofthe arm 65 and raised the solderingiron 5S) free and clear of the formedblank on the mandrel which is then approaching said soldering iron,during which time there is no longitudinal movement of the bar whichcarries lUtl llO

said soldering iron. The conguration of the remaining portion of thecam-groove 78 is such that when cam 67 has cleared the roller 66, andthe soldering iron 59 has been depressed against the formed blank on themandrel underneath the same, said groove will operate through the roller77 of the lever pivoted to the shaft 7 5 to reciprocate said bar andmove said soldering iron 59 back and forth along the overlapped orsuperposed edges of the blank.

The solder is in the form of wire strands and is preferably coiled uponthree spools 80, 81 and 82, having' axles which are suitably journaledin the bar 83 which is suitably fixed to the frame Q1. F rom each ofthese spools, a strand of wire passes upwardly and into correspondingguide-grooves in the idler roller 8st and thence, respectively, into theguide-tubes 85, 86 and 87. This idler roller 811 is loosely journaled onthe sleeve G53, and the guide-tubes 85, 86 and 87 are supportedindependently thereof in a manner hereinafter described. Theseguidetubes direct the ends of the strands of solder wire to properpositions underneath the soldering iron 59. This 'soldering iron (asbest shown in Figs. 7 and 13) comprises a casing which includes a lip 88which has an edge adapted to impinge against the end of each solder wireand bite off a certain quantity of the solder, which is then, throughthe longitudinal reciprocal movement of the hot soldering iron,distributed along the superposed edges of the formed blank. Thissolderingiron 59 may be heated in any desired manner. 'I have shown thesaine of hollo-w construction and having a fluid supply pipe 105 leadingto the same. This pipe 105 is secured to and forms a part of the supportfor said soldering iron and is therefore movable therewith. This pipemay be used to convey steam to the interior of said iron 59, or may beused to convey an inflammable gas to a suitable burner provided in theinterior of said iron.

lVithin the sleeve 63 is provided the inner shaft 89 (see Fig. 10), thisinner shaft 89 having a pin 90 projecting therethrough and throughoppositeh,7 located longitudinal slots 91 and 92 in said sleeve 68. Thispin 90 secures to said inner shaft 89 the grooved collar 93, while acorresponding pin 94E in said shaft 89 projects through the oppositeslots 95 and 9G in said sleeve G3 and secures to said inner shaft 89 theL-shaped frame 611. It will be apparent that the inner shaft 89 is thusslidable for a limited distance within the sleeve or outer shaft 63, andthrough the medium of the pin 9st in the slots 95 and 96, longitudinalmovement of said frame 6-1 and said loose idler roller Slt may beelfected without interference with the rocking movement of or slidingsaid sleeve 63. lt is desirable to effect the longitudinal reciprocationof the frame 64, which supports the guide-tubes 85, 86 and 87 andcarries the wire-feeding` mechanism, and therewith the idler roller 8l,in order that the ends of the wires, from each of which a small quantityof solder has just been severed, may be withdrawn from the hot solderingiron during reciprocal movement of the latter to properly distribute thedetached solder. To effect this operation, l provide a lever 97 pivotedat 98 to the bracket 99 on the frame 21 of the machine, one end of saidlever being provided with a roller 100 operating` in the groove 101 ofsaid collar 93, and the other end thereof being provided with a roller102 in cooperative positional relation to the cam 108 on the shaft- 68,said cam being of such configuration that upon rotation of said shaft G8the shaft 89, but not the sleeve G3, will be reciprocated. This shaft 89terminates short of the outer end of the sleeve, and interposed betweenthe ends of the former and the latter is the coil-spring 10st whichtends to return said shaft 89, and therewith the frame 6st and the idlerroll 81, to their original positions. Furthermore, the arm G5 isoperated by the cam 0T to rock said shaft 63 and raise the solderingiron 59 just prior to operation of the cam 103 to permit the return ofthe frame 6st and the idler roll 8st under action of the spring 101 tosuch position that the ends of the three solder wires are again inposition to be severed by the lip or cutting block 88 for the nextsucceeding soldering operation. AThen the cam 67 operates through thearm 65 to permit the lowering under gravity of the soldering iron 59,the cam 108 operates through the arm 97 to slide the frame 6-1 and theidler roll 8st against the action of the spring 10st and withdraw theends of the solder wires from proximity to the soldering iron 59 toprevent the fusing of an unnecessary amount of solder.

ln order to intermittently advance the solder wires to feed the endsthereof into proper position underneath the soldering iron, I looselymount upon the sleeve (33 the two arms of the frame 106, in oppositesides of which is journaled the shaft or rod 107 upon which are pivotedthree dogs, of which one 108 is best shown in Fig. 11, the others beingidentical thereto and each being so located that the sharp tooth thereofis in coperative positional relation to the strand of solder wire whichpasses thereunder and around the roller 84. A spring 109 keeps the teethof said dog in contact with the strand of solder wire. and it will beapparent that movement of said frame 106 in an upward direction willcause the dogs 108 to bite into said wires and advance the same, whileduring movement downwardly said wires will be released by said dogs.This frame is rotatable on the shaft 68 throuOh the medium of the arm110 secured to or forming a part of said frame,

to the free end of which arm is pivoted the rod 111 having a slot 112 inthe head 118 at its end, Within which slotrotates the shaft 68. The head118 of said rod 111 is provided with a pin 114-, While said shaft 168 isprovided With a cam 115 adapted to impinge against said pin and movesaid rod longitudinally to rock the frame 106 and raise the shaft 107,operating through the dogs 108 to advance the three strands of vv' "e aproper distance through their respective guide tubes.

The frame 641-, being secured to the inner shaft 80, reciprocates withsaid shaft and carries therewith the frame 106 bet-Ween the arms ofWhich is located the frame 64E and the idler roller 811-. Otherwise, theframe 641- is stationary. In this frame l provide a shaft 117 upon whichare mounted three spring-dogs, of Which the one 118 shown in lfig. 11 isidentical to all. These dogs bite the ivire after it has been advancedand prevent return thereof through movement in a downward direction ofthe dogs in the frame 106. lltroin a portion of this frame (Set projectsdownwardly a pin 119, limiting the rocking movement of said frame 106,and surrounding said pin 119 is a spring 120, in tension between saidframe 64 and the arm 121 of said frame 106 to return said frame to anormally operative position after said cam 115 has passed the pin 114.rll`he guide-tubes 86 and 87 are suit-ably carried by the frame 6st.

lt will nou7 be apparentthat with the soldering iron in its elevatedposition, as indicated in Fig. T, the mandrel carrying the formed blank,with su perposed edges clamped together, is brought thereunder, and theends of the solder Wires are in position to be engaged by the lip 88 ofthe descending iron. (F ig. rThe cam 67 now passes from under the roller66 (F ig. 7) and the iron 59 descends by gravity, severing a smallportion from the end of each solder Wire which is fused and depositedupon the edges of the blank. Immediately thereafter, the cam 103operates through the lever 07 to reciprocate the shaft 89 (Figs, 10 and14), carrying therewith the frames 641 and 106 and removing the ends ofthe solder Wires from close proximity to the hot soldering iron.

To check rotation of said head 83, and coilsctpientny to check movementof the formed blank during the soldering operation.` i provide the shaft80 with the fixed ratchet Wheel 122 having as many teeth as there aremandrels on said head 88. Fulerumed at 128 to a suitable part of theframe 21, is the lever 12-1, one arm thereof being provided With a pin125 adapted to successively engage the teeth in said ratchet eser/5a122, the other end of said lever being provided With a roller 126 in thepath of movement of the pin 127 on the disk Wheel 128 fixed upon theshaft 22. This pin 127 is so located on the Wheel. 128 that the roller126 is euOaged and the pin 125 Withdrawn from the notch in the ratchet122 just after coinpleting the soldering` operation, whereby the shaft80 is permitted to rotate through another step to bring the nextsucceeding formed blank under the soldering mechanism. A suitable spring171 may be employed to yieldingly force the arm 12st in the direction ofsaid ratchet. l have already explained that the horizontal shaft 24 isin two parts, coupled through the frictiondrive device 167, whereby Whensaid pin 125 is in engagement with one of the notches in the ratchet122, the bevel gear 25, and that portion of the shaft 24- to which it issecured, will run idly, the resistance of the pin 125 overcoming thefriction of the device 167, while Where the pin 125 is Withdrawn thefriction of the device 167 will drive the shaft and therewith the headAfter the mandrel carrying the can body which has just been soldered'hasbeen withdrawn from underneath the soldering iron, and as eachsucceeding formed blank is brought thereunder, the head 88 is permittedto rotate 9 three steps before the Withdrawal or ejectment of the formedbody, in order to permit the solder to cool and harden.

lt will be apparent that in order to strip the formed can body from themandrel, it will be first necessary to separate the arms 35 and 41through movement of the arm 87 which depresses said arm 85. Furthermore,the can body being thus released, must be stripped from the mandrel anddischarged into a chute or other suitable receptacle th -refoix Toaccomplish this, I provide a shaft 120, slida ble in suitable bearingsin the frame 21 of the machine and in the sleeve 180 which is similarlyslidable independent of said shaft 129. rlhis sleeve 130 is providedivith the two fixed collars 181 between which is retained the free endof the lever 182, fulcrumed at 138 to the frame 21 of the machine, andprovided intermediate its ends with the roller 181 in cooperativepositional relation to the cam 135 on the shaft 68. This cam 135 is ofconfiguration to effect and properly time recprocation of said lever132, said lever being yieldingly held against said cam through themedium of a suitable tension spring 186, whereby said sleeve 180 isreciprocated through a limited distance toy rotation of said shaft 68.This sleeve 130 is further provided With the collar 137, adapted uponreciprocation to impinge against the end of the lever 188 fulcrumed at139, the other end 1110 of Which is adapted to be brought into the pathof movement of one of the rollers l2 at the proper time to forceinwardly the arm 37, thereby depress ing the arm 35 and releasing theformed borlv.

The inner shaft 129, is reciproca-ted by means of the lever 141,fulcrumed at 142 to the frame 21 of the machine, to which is pivoted thea 1m 143, the other end of which is pivoted at 144 to the body of thecam 135. To the other end of the shaft 129 is secured the bar 145 whichis provided with the upwardly directed arms 146 and 147, at the ends ofwhich are suitably provided the spring-dogs 14S and 149 adapted to enterthe longitudinal grooves 150 and 151 in the mandrel 34. It will beapparent that as the shaft 129 is reciprocated to the right(referringnow to Fig. 3) the dogs 14S and 149 (see also Figs. 17 and 18)will yield to the interposed can body, but will spring into said grooveswhen said can body has been passed. As said shaft 129 is reciprocated tothe left, said dogs, having entered said grooves, will engage the endsof the can body and strip the same from said mandrel and upon the chute152, which may be so shaped and adjusted as to deliver-said can body toany desired point. The mandrel from which the can body has just beenstripped will now be carried forward one step to the position where itis ready for the positioning of another formed blank.

It will be apparent that there may at times be some delay in adjustingthe formed blank upon the mandrel which has been brought into positionfor this operation. lin order that the same may not be carried forwarduntil said blank has been properly treated with the iiuxing solution andadjusted, as described, provide a bar 153 having a slot 154 within whichis located the pin 155 on the frame 21 of the machine one end of saidbar being loosely retained between the pins 156 and 157 on the rod 158which is pivoted to the treadle 47. Then the rod 4S is depressed,through depression of said treadle, t-hisbar 153 being fulcrumed at 155,the other end thereof is brought into the path of movement of the stop159 on the gear 70 (see Fig. 15). The slot 154 provides for somemovement of the gear 17 0 after engagement between the pin 159 and theend of said bar 153, and such movement causes the pin 160 on said bar153 to impinge against the lever 161 and release a suitable clutch 162thereby causing the vpulley 23 to run loosely upon the shaft In thismanner, not only is the power shut oif, but the machine is positivelystopped for proper adjustment of a formed blank upon the proper mandrel.he clutchoperating lever 161 is provided with an accessible handle 163for hand operation of the same when desired. A spring 164, in tensionbetween the pin 165 at the end of returns the shaft 129 to its originalposition after operation of the arm 141.

I prefer that in the top face of the reciprocating arm 35, at the top ofthe mandrel 34, there be placed a strip 170 of enamel or similarcomposition, to which solder, upon cooling will not adhere-as it does tometal. Otherwise the soldered can body would be likely to adhere attimes to the arm and prevent ej ectment thereof.

)Vith respect to the present inventio-n, it will be noted: first, thatthe mandrels are readily detachable from the rotating head and,therefore, may be easily removed either for repair or for replacement bymandrels of different sizes and shapes; and, furthermore, that the block40 may be similarly removed from the permanent arm 41 if necessary ordesirable to adapt the machine for the soldering of can bodies ofdifferent size or shape; second, that the solder-feed device is underpositive control, and the length of that portion of the end of eachsolder wire which is fed beneath the soldering iron may be easily variedto suit the requirements; third, that the rotating head, being,frictionally driven, may be readily stopped at any time either with orwithout stepping the other moving mechanisms of the machine, andautomatically for predetermined intervals of time to enable a formedblank to be placed upon the proper mandrel and for the solderingoperation; fourth, that said solder feed device is positivelyreciprocated to and from its operative position, for the reasons,explained; and, fifth, that the stop mechanisn'i-that is, the mechanismfor operating the clutch and throwing off the power--is not only undermanual control, but is also automatically operated in case there isdelay in properly adjusting a formed blank upon the mandrel.

Many modifications of minor details of my improved soldering machinewill doubtless readily suggest themselves to those skilled in the art towhich it appertains, and I therefore do not desire to limit my inventionto the specific construction herein shown and described.

I claim as new and desire to secure by Letters Patent:
